The Cat and Mouse Game: Modern Fraud in Technical Hiring
In remote recruitment, security isn't just about proctoring—it's about staying one step ahead of a highly motivated adversarial market.
Let's be honest: If a six-figure salary is on the line, someone, somewhere, is going to try to cheat the system.
Over the last two years, interview fraud has shifted from amateur "notes on a sticky-note" to professional-grade proxy networks. We are now seeing specialized services where candidates pay a fee to a "ghost interviewer" who takes the technical screen on their behalf.
If you're still relying on "camera-on" as your only security measure, you're already compromised.
The Forensic Red Flags
Detection today isn't about catching a person "looking away." It's about analyzing the telemetry of technical truth. Here are the sophisticated signals we track to differentiate a honest candidate from a proxy.
Input Pattern Dissonance
Does the candidate's speaking speed match their coding speed? Proxy actors often types in "bursts" (copy-paste) while trying to maintain a slow, conversational dialogue. This dissonance is a primary signal of fraud.
Latency Artifacts
When a candidate uses a hidden virtual machine or screen-share to receive help, there is a systematic lag in their responses. It looks like "thinking," but the mathematical frequency of the delay doesn't match biological thought patterns.
Advanced Detection Strategies
We move beyond basic proctoring. We treat every interview as an authenticated session.
Behavioral Fingerprinting
Identifying the unique "style" of an engineer. How they debug, how they comment, even how they use whitespace. Proxy actors struggle to replicate a candidate's historical coding behavior.
Adversarial Integrity Layer
Our Sentinel Forensics injects non-obvious technical traps into the interview. A proxy actor following a script will often ignore these traps, while a real engineer will find them immediately suspicious.
A Note on Legal Ethics
We believe that security should never come at the cost of candidate dignity.
The Sentinel Promise: We do not track keystrokes outside the interview environment. We do not use "black-box" scoring. If a fraud flag is raised, we provide a detailed forensic report explaining exactly which signal triggered the alert, allowing for human review and rebuttal. Fairness is our primary metric.
Conclusion
In technical hiring, trust is expensive. It must be earned through verified skill and identity. By deploying a forensic-first security layer, you don't just stop cheaters—you protect your team's time and your company's long-term engineering excellence.
